Storage device for umbrella sacks

ABSTRACT

The storage device for umbrellas sacks of the present invention comprises: a body where a number of storage sacks are stored; a movable support base arranged to move vertically in the body; a wear plate that makes said movable support base lower when it contacts an edge of an umbrella; and open control levers that open the storage sacks in the descending motion of said movable support base. The storage device is structured so that the umbrella can be automatically inserted in the storage sack when the open control levers open the storage sack in the descending motion of the movable support base by contacting the wear plate with the edge of the umbrella. The wear plate simultaneously sweeps back by rotating downward.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a storage device for wet umbrellas that automatically wraps the umbrella in a sack. It can be used, for example, at an entrance of hotels, shops and department stores, so that, when it is raining, the umbrella can be adequately handled and stored.

2. Description of the Prior Art

When it is raining, synthetic resin sacks (plastic sacks) have, traditionally, been used to wrap wet umbrellas in order to avoid wetting clothes, floors or good while the customers walk around carrying wet umbrellas inside hotels, shops or department stores.

As shown in Japanese Patent Application No. 60-134817, Japanese Utility Model Publication No. 62-125708 and Japanese Patent Application No. 4-31222, a variety of storage devices, that can open a storage sack and store an umbrella by just inserting the umbrella into an opening, have been proposed to ease the storage operation.

In the prior method, as mentioned above, there can be complex structure problems as a result of the negative pressure suction, as a means to open the storage sacks, with the number of links, or with the cam mechanism. In addition, because a vacuum pump or a motor is used, the production cost increases and such devices cannot be used where a power source is not available close to the devices. Power cords are a hindrance and there is danger of a short circuit when the devices are operated and it is raining.

In consideration of the above-mentioned problems, the present invention is proposed to solve such problems. With regards to the present invention, no power source is required. The invention provides a simple structured device so that umbrellas can easily be stored in storage sacks.

BRIEF DESCRIPTION OF THE INVENTION

As the storage sacks used in the device, the upper open end of the sacks and the upper fore side of the sack opening is folded and the upper rear side is projected above that of the fore side and locking holes are provided at the upper side of such projected portion.

In one embodiment of the present invention, a number of storage sacks are charged in a storage device and the openings of said sacks are open so that each umbrella can be stored in such a sack. A box, in which a number of storage sacks are stored, is charged into the storage device. Such a structure is one of preferred embodiments of the present invention. In this case, the selected embodiment of the storage sack is that the sacks are retained in such a box by suspending such sacks with a hanger.

In addition, according to embodiments of the open control levers, a pair of open control levers are provided to move and rotate independently for the above-mentioned movable support member. In this case, with regards to means for moving and rotating the open control levers in a certain direction to contact with storage sacks charged in the storage device, preferred means are provided independently for each lever.

Besides, the open control levers can be comprised of a bucket-shaped member made with a non-friction material (e.g. resin materials such as plastic). In this case, a structure of the device body is not limited to a casing structure. For example, it can be structured using only pillars. Transparent members can be arranged between such pillars.

According to the above mentioned structure of the umbrella sack storage device of the present invention, the open control levers open the sacks by contacting each edge of the umbrella to be stored with the wear plate and by lowering the movable support base. Simultaneously, the wear plate sweeps back by rotating downward in order to insert each umbrellas automatically into each storage sack. As a result, storing umbrellas into storage sacks is carried out without using a motor.

In addition, according to the storage sacks of the present invention, a number of storage sacks can be retained in the device by providing a cylindrical hanger to suspend them through the locking holes provided at an upper edge of the projected portion. The open control levers can be inserted into the openings reliably in order to open such opening by folding the upper end of the fore side sack opening.

According to the prior art, a number of storage sacks are simply piled up to charge them into the storage device, and it is often difficult to store them due to dispersion problems. Besides, it is not easy to store or carry a number of such storage sacks before they are charged into the storage device. However, according to the storage device for umbrella sacks of the present invention, in which a number of storage sacks are stored, such storage sacks can be charged into the storage device. In this case, it is possible to charge a larger number of storage sacks at once, easily and rapidly. Besides, it is easy to store or carry many sacks before they are charged into the storage device since they are packed in one box.

In the present invention, when the open control levers are structured as a pair of open control levers and move and rotate independently from the movable support member and when the means are structured independently for each lever, as it makes the open control levers move and rotate in the direction to contact with the storage sacks charged in the storage device, the opening will be certainly open despite the misregistration that can be generated around the opening.

On the other hand, when the open control levers are structured by bucket-shaped members, formed with slippery materials, such as, resin materials, e.g., plastic, the insertion of umbrellas can be done easier and with greater certainty.

On the other hand, as shown in FIGS. 7A, 7B, the upper part of a storage sack 5 has an opening 5a; the upper end 51a of the fore side 51 of the opening is folded forward or may be folded backward in a U-shape; the upper end 52a of the rear side 52 is projected above the upper edge of the fore side 51; and a pair of locking holes 5b are provided at the upper end of the projected portion of rear end 52a.

As shown in FIG. 2 and FIG. 4, a number of storage sacks are suspended in order to retain them by inserting each opposing arm of the aforementioned box type hanger 6 into each locking hole 5b.

A pressure plate 9, FIG. 2, is movably installed along a pair of guide bars 10, 10 on the rear face of storage sacks 5 and pressure plate 9 is constantly pressed to the rear face of storage sacks 5 by a coil spring 10a on each guide bar.

As shown in FIG. 2 and FIG. 3, a box type guide rail 13 is installed, vertically, at one horizontal end of the front face of the fixed support base 4; a support member 14 is installed, vertically, at the other horizontal end of the front face of the base 4; and a movable support base 11 is arranged on the front face of the fixed support base 4.

A rotating roller 12, which is rotatably arranged at one end of the movable support base 11, is positioned in the guide rail 13; as shown in FIG. 3, a pair of long holes 16, 16 are vertically formed on the box type guide member 15 mounted on the other end of the movable support base 11; and the movable support base 11 is retained vertically to the fixed support base 4 by hitching a grooved roller 17 to the support member 14.

Additionally, a pair of pulleys 18, 18 are installed vertically on support member 14 in front of the guide member 15 as shown in FIG. 2 and FIG. 5; the plumb 20 is mounted by screws 20a, 20a on one side of tense belt 19 and rotated with both pulleys 18, 18; and the movable support base 11 constantly moves vertically by connecting the other side of belt 19 with connecting member 21 fixed to guide member 15 using screws 21a, 21a. A stopper is mounted on the fixed support base 4 for anchoring the movable support base 11 at the fixed ascending position as shown in FIG. 3 so as to limit the ascending motion of movable support base 11. In FIG. 2 and FIG. 3, stoppers 13a and 14a are formed by bending one end of the guide rail 13 and support member 14 in a forward direction so as to limit the descending motion of the movable support base 11.

A shown in FIG. 2 and FIG. 4, a pair of supporting shafts 23, 24 are provided on the upper central front face of the movable support base 11 through a bearing 16. A wear plate 25, which lowers the movable support base 11 by contacting with a shoe at the edge of umbrella, is provided on a supporting shaft 23.

Concave 25a, which contacts with the shoe at the edge of the umbrella, is formed on the upper central face of the wear plate 25. As shown in FIG. 4, a curvature 25b is suspended vertically from a position between the movable support base 11 and the fixed support base 4, and the curvature 25b is provided at the rear part of the wear plate 25.

At the bottom of the curvature 25b, a roller 27 is provided through an shaft 26 anchored by welding and the like. The upper face of the wear plate can be retained horizontally by contacting the roller 27 with the front face of the fixed support base 4.

Besides, a pair of open control levers 28, 28 which open the sack openings by entering into the opening 5a of the storage sack 5, are provided on the other supporting shaft 24 to be movable in both sides of the wear plate 25; the both levers 28, 28 are connected by means of a connecting arm 29, which is fixed to upper ends of said levers by welding and the like. In addition, the pair of open control levers 28, 28 can be made as independently movable relative to the arm 29, however, an embodiment of such movable levers 28, 28 is not shown in the present application.

As shown in FIG. 2, the structure is such that one end 29a of the connecting arm 29 bends forward; and by mounting a plumb 30 at the end of the curvature 29a, the open control lever 28 rotates in counterclockwise direction in FIG. 4; the lower end of the lever 28 is pressed to the front face of fore-front storage sack suspended by hanger 6.

In lower curvature 29a of said connecting arm 29, a connecting plate 31, which rotates the open control lever 28 in a clockwise direction in FIG. 4, is integrally provided on the front face of guide rail 13.

In the aforementioned structure, upon storing an umbrella U in the storage sack 5, as shown in FIG. 8a, press the umbrella U downward by contacting the shoe U1 of the edge of umbrella U with the upper face of the concave part 25a of the wear plate 25; and the roller 27, provided on the curvature 25b of the wear plate 25, as shown in FIG. 8B, moves downward together with the movable support base 11 against the ascending force power with the plumb 20, while contacting the roller 27 with the front face of the fixed support base 4 keeping the upper face of the wear plate 25 horizontal.

Accordingly, the open control lever 28 moves downward while pressing the end 28a on the upper front face of the opening 5a of the forefront storage sack 5; and then the end 28a of the open control lever 28 enters the opening 5a of the storage sack 5; in this case, should the upper part 51a of the fore side 51 be folded as mentioned above, the end 28a of the lever 28 can definitely enter into the opening 5a.

When the open control lever 28 further moves downward and the end 28a is entering into the opening 5a, the front side 51 of the storage sack 5 is gradually pulled outward and forward and the upper part 51a of the front side 51 enters into the concave area 28b on the open control lever 28, as shown in FIG. 8B. Simultaneously, the curvature 29a of the connecting arm 29 contacts with the connecting plate 31.

In the same state, when the open control lever 28 further moves downward, together with the movable support base 11, the open control lever 28 and the connecting arm 29 rotate in clockwise direction in FIG. 8B around the supporting shaft 24 against the descending force of the plumb 30. The opening 5a of the storage sack 5 opens wide, as shown in FIG. 8C, while entering the upper part 51a of the front side 51 of storage sack 5 into the concave area 28b of the open control lever 28.

Simultaneously, the wear plate 25 is lowered. The roller 27, provided on the curvature 25b of the wear plate 25, is removed from the central convex 4a (See FIG. 3) of the fixed support base 4. As shown in FIG. 8C, the wear plate 25 sweeps back by rotating in counterclockwise direction around the supporting shaft 23. As a result, the shoe U1 of the edge of umbrella U enters the storage sack 5 by slipping on the upper face of the wear plate 25 from the concave area 25a of the wear plate 25; and finally, the umbrella U is automatically stored in the storage sack 5 by further lowering the umbrella U.

The sack 5, in which the umbrella U is stored, can easily be taken out together with the umbrella U by pulling it out while lowering the device body 1 to remove the upper locking holes 5b of the storage sack 5 from the hanger 6.

Additionally, the movable support base 11 and the open control lever 28 automatically return as they are with plumbs 20, 30 by removing the umbrella U stored in the sack 5 forward. The roller 27, provided on the curvature 25b of the wear plate 25, moves in front of the fixed support base 4; and the wear plate 25 returns horizontally to a standby state.

As mentioned above, according to the present invention, umbrellas can easily be completely stored in each storage sack without using a motor or a vacuum pump to open the openings of the storage sacks.

The aforementioned embodiment is just an example, therefore, and structural changes on the aforementioned members are possible within the purpose of the present invention. For example, in the above preferred embodiment, rollers 12, 17 and long hole 16 are applied as a means to movably retain the movable support base 11 vertically. However, there are no limits to these means. Besides, plumbs 20, 30 are applied as means to ascend the movable support base 11 and to press the open control lever 28 to storage sack 5. However, another member, such as a spring, can be used.

The other embodiment regarding the present invention is explained in the following, referring to FIG. 9 through FIG. 13:

FIG. 9 shows storage sack 104 applied in the embodiment. The storage sack 104 is formed from plastic film, and the like, to be flat cylinder-shaped; an opening 104a is provided in the upper part of the sack. The upper part 141a of the front side 141 of the opening 104a is folded to the rear side in a U-shape; the upper part 142a of the rear side 142 is projected further up than that of the front side 141; and a pair of locking holes 104b are provided on the projected portion.

On the other hand, the aforementioned box 105, as shown in FIG. 10, is formed from corrugated fiberboard, and the like, and is longitudinally rectangular-shaped. A pair of bar-shaped hangers 107 are provided in the upper part inside the box 105.

A number of storage sacks 104 are suspended facing the fore side 141, on the left-hand side in FIG. 11, to retain them by mounting the hanger 107, FIG. 11, penetrating the locking holes 104b of said storage sacks 104 on the supporting plates 108a, 108b anchored on the upper face inside box 105. A pressure plate 109 is arranged on the rear side of the storage sacks 104; the pressure plate 109 presses a number of storage sacks 104 on the left-hand side in FIG. 11 by elastic members. In FIG. 11, rubber bands 110 are applied as elastic members; both ends of the rubber bands 110 are anchored to hook 181 provided horizontally at opposite ends of supporting plate 108a.

As shown in FIG. 10, an opening 151 which can open along with perforating scores 105a is provided on the front face of the box 105; the box can be transferred and stored without opening the opening 151 when it is not used. When it is used, as shown in FIG. 12, after the opening 151 is open along with the perforating scores 105a, open the switch door 106 provided on the rear side of the device body 101 to fill the box 105, with the opening 151 opened, into the device body 101.

An unillustrated fixed support member is provided inside the device body on the upper part of the box 105 placed in this device body 101. The box is set in a fixed position by contacting the front side of the fixed support member with the front face of box 105.

As shown in the aforementioned embodiment, the box 105, storing storage sacks for umbrellas is filled from the rear side to the device body 101. However, the box can be filled from the top of the device body 101 by opening the aforementioned cover 103. In addition, with regard to box 105, it is not necessary to cover up the all faces of the box by the device body 101, as shown in FIG. 1 to FIG. 12. For example, as shown in FIG. 13, a frame body 101b can be applied as a part of the device body to fill the box 105 into the frame 101b to determine the specified position to retain the box.

Besides, in the aforementioned embodiment, it is explained that the opening 104a of storage sack 104 is open by operating the open control levers 122. However, it can be opened by actuating vacuum suction in the prior embodiment.

FIGS. 14 to 16 show the other embodiments regarding the present invention. In FIGS. 14A and 14B, the character 128 shows a bucket-shaped member integrally formed from plastic. Umbrellas can be smoothly inserted thanks to the shape of this member. Opening storage sacks 5 by this bucket-shaped member is shown in FIGS. 15 and 16, however, a detailed explanation is skipped because the state shown in FIGS. 15 and 16 is almost the same as that in FIGS. 8A, 8B and 8C.

Furthermore, instead of the above illustrated embodiment, a pair of open control levers can be structured to independently move movable support member; and means, which moves in the direction to contact the levers with storage sacks stored in the device body, can be structured to set independently to each lever. Thus storage sacks can certainly be open even if some misregistration occurs in the opening.
